When Kalley's dad got a job a few years ago, that meant he would leave his home office. That idea didn't sit so well with her. So she drew a picture, and explained it to her family.

She said “It's a machine. It's a plan for a machine and if you can build this machine, it will make food for us so you don't have to go away any more,” Carrie Alexander, Kalley’s mom, told WLWT News 5.

Simple enough, right?

Carrie said the idea is perfectly within Kalley’s character.

“I mean it's just very typical of Kalley to see a problem and come up with a solution,” Carrie said.

It got the wheels turning for dad, Jon. He had been doing interactive and design work for years. But this was different.

"I was like, ‘Oh. Well the one thing I'm actually good at is making stuff that's fun to click on and that's what kids love,’ and I'm like, ‘Well, we can do that,’” Jon said.

From there, they drew and illustrated with a lot of help from big sister, Corbett.

“I just like making up stuff in my head and then just trying to draw it out on paper,” Corbett explained.

Then they wrote the story and made a video.

Now, they've landed in the App store and is available on Apple devices.

But the goal is to make ensure they continue do it all as a family.

"We think it's a valuable story beyond just our app. I mean, if it helps sell our app, that's great because that accomplishes our family vision, which is nice, but we love the idea of starting the conversation about priorities,” Jon said.

Carrie agreed.

"Not everybody's gonna make an app, but just figure out something that they can do together."
